TL;DR: In this paper, the authors considered the possibility that narrow absorption lines could arise naturally in the accretion disc and proposed a reflection-based interpretation for accreting black holes systems, which requires no high-velocity outflow/inflow.

TL;DR: In this article, a detailed spectral analysis combining the broad-band coverage provided by XMM-Newton+NuSTAR with a multi-epoch approach incorporating archival observations was carried out for the type 1.8 Seyfert galaxy IRAS.

TL;DR: In this paper, the authors examined the K shell emission lines produced by isothermal and simple multiphase models of the hot gas in elliptical galaxies and galaxy clusters to determine the most effective means for constraining the width of the differential emission measure, j(T ), in these systems which was characterized by a dimensionless parameter, sj.

TL;DR: In this paper, the authors used constraints imposed by the observed radio emission to obtain upper limits to the volume filling factors of wind components in certain nearby active galactic nuclei (AGN) this paper.

TL;DR: In this article, the authors present a deep Chandra observation of the extremely massive spiral galaxy 2MASX J23453268-0449256, the first X-ray observation of this very rare system which features the largest known relativistic jets from a spiral galaxy.
